    Is there such a thing floating around as a wiring diagram for the firewall of an 85 Blazer? I am going to clean up all the unnecessary wires and it would be a lot easier to do if I could tell what they were for without having to trace everyone down.

    Thanks

    Here are some diagrams MJ put up a while back. They should help.

    Those will help... but I am more looking for what is where on the engine compartment side of the firewall.

    So I can remove all the junk!

    Like a component locator diagram? That's about the only thing I know of that will show you what is located where. Anyway, you might check your main local library, they usually have old shop manuals, and such.

    Well on the engine side there is very little that isn't needed. Even with the emmisions stripped the only thing not needed is one wire for a valve and a wire for the mix solinoid if you have gone to a non electric carb. That wire is simesed in with the choke wire so not much point in removing it. The biggest wad of wires is for the wiper motor and you need EVERY wire or it will not work correctly. As for cleaning it up I would get either some plastic wire loom or the fabric tape for wraping them. That will clean it up. Your going to have to go to a GOOD big electronics supply house to get the fabric wrap. Great stuff for a show truck but it will get mud stained in a 4x4.
    Your bigger Library's usualy have Factory manuals for each year on Micro Fisch. 10 cent's a coppy for what you need. These are for each year because there are some little changes that happen that Haynes and Chiltons are not going to show.

    As Grim said, there isn't much "junk" to be had. Don't have any '85 truck stuff up, but this is an '85 car, I can assure you, the plugs are very similar.

    Why insist on counting when the ring gear has the tooth counts stamped in?
